The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Event 680; Error code 0xC0000064; Failed Logon

Asked by MitchV85 in Windows 2003 Server, Microsoft IIS Web Server, Windows Network Security

Tags: Windows Server 2003, IIS, WIndows Security

I am currently encountering an issue on a Windows Server 2003, Standard Edition, SP2 server that is running an FTP site in IIS. The Security log on this server is logging multiple Account Logon failure audits for two accounts. There is no set time interval for the occurance of these failed logon attempts, but they do occur approximately 65 times each day. The contents of the event log entry have been listed below:

Event Type:      Failure Audit
Event Source:      Security
Event Category:      Account Logon
Event ID:      680
Date:            2/4/2009
Time:            12:40:49 PM
User:            NT AUTHORITY\SYSTEM
Computer:      Server1
Description:
Logon attempt by:      MICROSOFT_AUTHENTICATION_PACKAGE_V1_0
 Logon account:      BobUser
 Source Workstation:      Server1
 Error Code:      0xC0000064

It is my understanding that the 0xC0000064 error code indicates that an account does not exist, however I have confirmed this account's existence in Active Directory. The account is not disabled and is not locked out.

Also, each time before this 680 event is logged, the following event occurs indicating a successful logon of the account in question:

Event Type:      Success Audit
Event Source:      Security
Event Category:      Logon/Logoff
Event ID:      576
Date:            2/4/2009
Time:            3:50:57 AM
User:            Domain1\BobUser
Computer:      Server1
Description:
Special privileges assigned to new logon:
       User Name:      BobUser
       Domain:            Domain1
       Logon ID:            (0x0,0x2BFF8836)
       Privileges:      SeTcbPrivilege
                  SeAssignPrimaryTokenPrivilege
                  SeImpersonatePrivilege
                  SeBackupPrivilege
                  SeRestorePrivilege
                  SeTakeOwnershipPrivilege
                  SeDebugPrivilege
                  SeSystemEnvironmentPrivilege
                  SeLoadDriverPrivilege
                  SeSecurityPrivilege


Thank you in advance to anyone who can provide some insight into this issue as I am currently stumped.
